How sharks make little sharks

Sharks have three modes of reproduction and in all three provide no form of parental care. Generally, sharks bear live young however there are some sharks lay eggs. Viviparity, live birth, is the most advanced form. The female provides nourishment for the embryos as they develop inside of her. The nourishment can be delivered as a secretion called uterine milk or through a placenta. Hammerheads are a good example. At birth the young look like miniatures of the adults, sometimes up to two or three feet long and weighing a maximum of 40 pounds.
